This invention relates generally to coin operated vending machines and more particularly to an improved coin detector and change making mechanism.

Briefly described, the invention comprises means for mechanically rejecting a coin inserted in a change making vending machine when there are insufficient coins remaining in the machine to make proper change for the coin deposited.

In change makers there is provided a vertically positioned tube adapted to receive coins on operation of the vending machine which coins are dispensed from the machine in making change, when the machine is operated with coins of larger denomination, requiring change. The coins must lie horizontally in the tube in a vertical stack for proper operation of the change maker. Coin detectors, heretofore provided for vending machines, have means extending into the coin tube and engage the edges of coins falling therein. Such means tend to tip each coin inserted thus precluding proper loading and operation of the coin tube.

When there is a sufiicient number of coins in the coin tube for making desired change, the coin detector is urged out of the tube by an inserted coin preconditioning the vending machine for operation and change making. When the number of coins in the coin tube is reduced to an insufficient number for making desired change, the coin detector is positioned to reject inserted coins and to lock the vending machine against operation.

Other change making mechanisms have been provided for vending machines for detecting when there are insufficient coins in the machine to make proper change but these have been electrically operated with intricate electrical switches, actuators and electrical operating circuits which frequently get out of order and are a source of considerable expense. These electrically operated coin detectors are not only expensive to manufacture and difficult to assemble, but are not dependable in their operation. Such switches operate by the weight of a coin imposed thereon, which weight is insuflicient to operate mechanical detectors and in many instances insufficient dependably to operate the electrical switches.

Therefore, it is an object of the present in- 2 vention to provide a coin changing mechanism for vending machines which is dependable in detecting the presence and absence of change making coins in desired quantity.

Another object of the invention is to provide a coin detector mechanism which does not impede the proper horizontal locating and vertical stacking of the change coins as they fall into a coin tube.

Another object is to provide means for withdrawing a coin detector finger from the change making coin tube during the period of time that a coin is gravitating into the tube.

Another object of the invention is to provide a dependable mechanical means for preventing operation of a change making device when the change making magazine contains an insufficient number of coins for the making of change.

Another object is to provide a coin detector that is responsive to coin position independent of the weight of the coin.

A still further object is to provide a coin detector that is economical to manufacture, easy to assemble, and is dependably automatic in its operation.

Other objects and advantages of the present invention will become apparent in the following description.

Th essence of the present invention resides in the provision of means in a coin change making and/ or vending mechanism that locks the mechanism against operation when there is less than a predetermined quantity of coins in the mecha nism for change making purposes, that rejects coins of a denomination for which there is an insuflicient quantity of coins in the mechanism for change making purposes while accepting coins of smaller denomination, which employs coins of various denomination to interlock change making means, and which in determining the quantity of coins in the mechanism available for change making purposes contacts such coins while they are at rest and thus avoids interference with coin movement and stacked accumulation in a change accumulating magazine. The device of the present invention is best understood in its operational environment. Thus preliminary attention is devoted to an explanation of the environment which is provided for illustrative purposes and not by way of limitation.

Referring in greater detail to the construction as illustrated in the drawings and more particularly to Fig. 1, the coin responsive mechanism, with which the coin detector of the present invention is employed, comprises a rectangular casing l0 enclosing a housing, indicated generally by the reference numeral II, having a back plate l2 and an upper compartment l3 partially enclosed by parallel side plates l formed integrally with the back plate and extending forwardly therefrom. A lower compartment i6 is partially enclosed by parallel side plates l1 formed integrally with the back plate 12 and extending forwardly therefrom. The lower compartment 16 is also provided with a bottom plate l8 attached to and extending horizontally between the lower edges of the side plates ll.

vend objects such as bottled beverages in responseto the insertion of a nickel, dime or quarter and to reject all spurious objects. When a dime or quarter is inserted into the vending machine, the machine is adapted to vend the desired commodity and the appropriate change. Whenever there is an insufficient number of nickels in the coin mechanism for making change, the dimes and quarters inserted into the slug rejector are returned by a mechanism hereinafter described and no vending operation performed.

Each nickel that is deposited or inserted at 20 into the slug rejector I9, falls through the rejector, along the dash line indicated by the reference numeral 2| and precipitates from the lower right hand corner of the rejector, as viewed in Fig. 1 of the drawing. Each ten cent coin or dime that is inserted into the rejector falls through the rejector along the dash-dot line, indicated by the reference numeral 22, and precipitates from the lower right hand corner of the rejector. Each quarter that is deposited into the slug rejector falls through the rejector along the dash-dot-dot line, indicated by the reference numeral 24, and precipitates from the rejector at its lower right hand corner. The segregation of the nickels, dimes, and quarters is accomplished in any convenient manner, conventional or otherwise, and is not described in greater detail.

The coin mechanism is provided with a horizontally extending vending machine operating shaft 26 which is rotatably mounted between the back plate 12 and a front plate 21 attached at 28 in spaced parallel relation to the back plate. On rotation of the shaft 26 sufliciently, an article of merchandise, such as a bottled beverage, is vended from a vending machine, not shown, associated with the coin mechanism of the present invention. The shaft 26 is manually operable by means of a lever 29 attached to and extending radially from the shaft. A plurality of vertically extending slots 30 are formed through a disk 3! attached in concentric relation to the shaft 26. Each of the slots 30 is adapted to receive a coin of a predetermined denomination and to guide the coin downwardly as it precipitates to its proper position.

Nickels passing through their individual slot 3c in the disk 3| are guided into the upper end of a vertically positioned cylindrical coin tube 35. Whenever the coin tube becomes filled, all nickels subsequently descending to the tube thereafter fall into the upper end of an overfiow chute 36 which is attached at 3'! to one of the side plates ll. All dimes passing through their individual slot 30 in the disk 3| are guided by the disk into the upper end of a dime coin chute 39 and gravitate downwardly to the lower end of the chute. All quarters passing through their respective slot 36 in the disk 3l precipitate into the upper end of a quarter coin chute 4t and gravitate to the lower end of the chute.

A slide mechanism, indicated generally by the The nickel coin tube 35 extends downwardly into and is secured to the supporting plate 48. An

operating slide 52 is slidably guided horizontally and longitudinally between the slide guides .46 and has a dime slot 53 and a longitudinally spaced quarter slot 54 formed vertically through and extending transversely of the operating slide. Said slots are adapted to receive their respective .5 coins on edge as they descend from their respective chutes 39 and 49.

A dime operable slide 55 is longitudinally slidably guided between the slide guides 46 with a portion of the operating slide 52 overlapping or superimposed on a portion of the dime slide. The dime slide has a dime slot 51, and a quarter slot 59 longitudinally spaced therefrom, formed vertically and transversely through the dime slide to receive their respective coins on edge, as shown in Fig. 2. The dime slide 56 also has a nickel receiving pocket 59 formed vertically therethrough which is normally located under the lower end of the nickel coin tube 35 and is adapted to receive individual nickels from the coin tube. A quarter operable slide 62 is longitudinally slidably guided between the slide guides 49 with a portion of the quarter slide superimposed on a portion of both the operating slide 52 and the dime slide 56. The quarter operable slide 52 has a quarter receiving slot 69 formed vertically and transversely therethrough and a cylindrical pocket 64 formed vertically therethrough, adapted to contain three nickels received from the bottom of the coin tube.

The dime coin slots 53 and 51 are normally in vertical alignment directly beneath the lower end of the dime chute 39 adapted to receive a dime from the dime coin chute vertically therein against the upper side of the bottom plate I8, providing horizontal driving connection between the operating slide 52 and the dime operable slide 59. The quarter slots 63, 54, and 58, when their respective members are at rest, are located in vertical alignment directly beneath the lower end of the quarter chute 49 adapted to receive a quarter vertically therein rested on the bottom plate I 3 and providing horizontal driving connection between the operating slide and both the dime operated slide 56 and the quarter operated slide 92.

The pocket 59, in the dime slide, and the pocket M, in the quarter slide, are located, when their respective members are at rest, in vertical alignment directly beneath the lower end of the nickel coin tube 35 adapted to receive nickels gravitationally from the coin tube.

The bottom plate It of the lower compartment 19 is provided with a cylindrical passage 9'! formed vertically therethrough through which coins are adapted to gravitate from the pockets 59 and 65 in the dime operated slide 56 and the quarter operated slide 62, respectively. A change receptacle 99 is secured to the underside of the bottom plate is in vertical alignment with the passage 97 located to receive change making nickels from the pockets 59 and 64. The bottom plate I8 has a dime depositing slot 10 and a longitudinally spaced quarter depositing slot I2 formed vertically and transversely therethrough located above a removable coin depositing box 13 supported on a portion of the case I9 of the coin mechanism. The slots 19 and I2 are adapted respectively to receive individual dimes and quarters therethrough when either of the aligned dime slots 53 and 51 or the aligned quarter slots 59, 58 and. 99 are located in vertical alignment therewith thus depositing the coins therefrom into the coin depositing box I3.

Means are provided by movement thereof for actuating the operating slide 52 horizontally to the left, as viewed in Fig. 2 of the drawing, from its normal rest position to coin depositing position. This means comprises a cam member I attached to the shaft 26 having a cam slot I6 formed horizontally through the member. A lever95 is pivotally connected at 8B to a portion of the housing Hand has a cam follower 81 rotatably connected to one end of the lever and guidably received into the cam slot 16 and movable thereby. A pin 88 is secured to the opposite end of the lever which is located in a slot 99 formed through one end of a link 9|. The other end of the link BI is pivotally connected at 92 to the upper end of alever 94 which in turn is pivotally connected at 95 to the back plate I2 of the housing. A helical tension spring 96 is connected at one end to one of the side plates I1 of the lower compartment and connected at its other end to the pivotal connection 92 so that the lever 94 and coacting members are yieldably held in their normal rest positions as illustrated in Fig. 2 of the drawings. The lower end of the lever 94 is provided with a circular head 9'! which extends downwardly into a cylindrical opening 98 formed vertically through the operating slide 52 so that the lever 94 and the operating slide 52 are operatively associated.

Means are provided for locking the vending machine operating shaft 29 against sufficient rotation to operate the vending machine when no coin or a spurious object is deposited in the mechanism. As shown in Fig. 2, this means comprises an approximately circular latch plate 99 secured concentrically to the vending machine operating shaft 26 and having a notched or hooked portion I 99 formed in the periphery thereof. A roller I9! is rotatably mounted at the outer end of a lever I92 rotatably mounted on a shaft I 93 extending horizontally between the back plate I2 of the housing and the front plate 21 of the lower compartment in a position to engage the latch plate hook I99 upon rotation of the latch plate from its normal rest position, as for vending purposes. Another lever I99 is pivotally mounted on the shaft I93 in operative contact with the lever I92 with the upper end of a rod I91 pivotally connected at I93 to its outer end. Referring to Fig. 6, the lower end of the rod I9! is pivotally connected at I99 to a leg of a bell crank lever I I I which is pivotally mounted at II2 to the back plate I2 of the housing. A substantially horizontally located rod I I3 is pivotally connected at I I4 to the opposite leg of the bell crank lever with the opposite end of the rod connected to one end of a pin 1 I5 which is secured horizontally through the dime operable slide 56. The pin II5 extends through a pair of relatively horizontally located slots l I 6 formed horizontally and transversely of the slide guides 49. A knob II! is secured to the outer end of the pin I I5 so that the dime operable slide may be moved manually by a service man, a repair man, Or other person having access to the knob, by manually reciprocating the slide and unloading the coin tube.

A coin rejecting lever I29, as shown in Figs. 2, 3, and 4 of the drawings, is located adjacent the rear side of the slug rejector I 9 within the upper compartment I3 and is pivotally mounted at I2I on a bracket I22 secured to the forward face of the back plate I2 of the housing. This coin rejecting lever I29 is provided with a quarter rejecting finger I24 and a dime rejecting finger I25 adapted to extend into the path 24 of the quarters and the path 22 of the dimes, respectively, to divert their respective coins, when extended into said path causing the contacted coins to be rejected from the slug rejector out of the lower left hand corner thereof, as viewed in Fig. 1 of the drawing and returned to the operator of the machine. The coin rejecting lever I29 is provided with an integral upwardly extending short leg Izl with a tension spring I28 connected between the leg and the bracket I22 yieldably urging the coin rejecting lever to coin diverting position. The coin rejecting lever I20 is movable to inoperative or ineffective position by means of a short arm I30 formed integrally with the coin rejecting lever I20 and rearwardly extended therefrom. A substantially vertically located rod I3I is slidably extended upwardly through an opening formed through the arm I30. A collar I33 is secured in circumscribing relation to the rod I3I which engage the under side of the arm I30 on upward actuation of the rod I3I moving the coin rejecting lever I20 to ineffective or retracted position.

The coin detector mechanism of the present invention, as is best shown in Figs. 5, 9, 10, and 11 of the drawings, comprises a coin detector finger I35 pivotally mounted at I36 to a bracket I31 secured in circumscribing relation to the coin tube 35. The coin detector finger is provided with a substantially horizontally extending arm I38 with the lower end of the rod I3I pivotally connected at I39 to the outer end thereof. The finger is also provided with a downwardly extending, triangular portion I40 adapted to enter into the lower end of the coin tube 35 through a slot I4I formed vertically through the lower end thereof. The weight of the rod [SI and the arm I38 of the coin detector plate I35 urges the finger rotatably around its pivot I36 in a counterclockwise direction, as viewed in Figs. 9, 10, and 11, to extend the triangular portion I40 into the lower end of the coin tube 35 through the slot I4I.

As nickels are received into the upper end of the coin tube they precipitate into the pocket 50 of the dime slide 56 and into the pocket 64 in the quarter slide 62 and when the stack of nickels is of such a height that there are nickels located adjacent the lower end of the triangular portion I 40 of the finger, the finger is retained in a partially withdrawn position by abutment with the near edges of the nickels stacked in the coin tube to a predetermined height.

Means are provided for moving the triangular portion I of the finger to a fully withdrawn position exteriorly of the lower end of the coin tube 35 during the period that a coin is precipitated into the coin tube so that the coin detector finger willnot interfere with the fall of the coin. This is significant in that any interference or contact with a coin descending into the tube has been found to tip the coin and frequently to lodge coins on edge in the magazine. The means for withdrawing the triangular plate portion I40 of the coin detector finger comprise a substantially horizontally located slide rod I45 located adjacent the back plate I2 of the coin mechanism which is guided for longitudinal sliding motion in a pair of guide brackets I46 each of which is screwed at I 41 to the back plate. The slide rod is bent upwardly forming a cam portion I48 and thence to a horizontal position forming a horizontally located raised portion I49 at the'end of the slide rod adjacent to the coin tube. The slide rod isbent to a horizontal forwardly extending portion I50 which is secured transversely through the outer end of the operatin slide 52 with the rod portion I50 guided for horizontal sliding motion in a pair of relatively horizontally located slots II formed horizontally and longitudinally in each of the slide guide 46. The arm I38 of the coin detector finger I35 rests on the upper side of the slide rod I45, at rest in the position as shownin Fig. 2 of the drawings'at the lower end ofthe camportion I48. .111 this position the portion..l.40: or.'the.cam detector finger extends into change making cycle.

8.. the coin tube. The triangular plate portion I40 of the coin detector finger is moved to fully withdrawn position exteriorly of the lower end of the coin tube 35 by horizontal longitudinal sliding motion of the slide rod I45 on horizontal longitudinal sliding motion of the operating slide 52 actuated on rotation of the operating lever 29 and shaft 26 by means of the cam slot I6, cam follower 81, lever 85, link 9 I, and the lever 94 connected to the operating slide 52.

Operation In the operation of the coin detecting mechanism as shown and described, the mechanism may be operated by the insertion of the nickel or five-cent coin into the upper end of the slug rejector I9 with the nickel gravitating through the slug rejector along the dash line 2I, indicated in Fig. 1 of the drawings, and moving to the lower right hand corner of the slug rejector. The nickel gravitates downwardly from the slug rerejector into one of the slots 30 in the disc 3I, with the upper arcuate edge of the nickel engaging partially under the roller IOI on the lever I02 as shown in Fig. 2 of the drawings. The vending machine operating lever 29 is manually rotated in a downward, or clockwise, direction as viewed in Fig. l, which causes the periphery of the nickel lodged in the slot 30 of the disc 3I to cam the roller I0! outwardly relative to the operating shaft 26 thereby freeing the roller from the hooked portion I00 and the shaft for continued rotation, as for a complete vending or The continued clockwise rotation of the shaft 26 pivots the lever which, through the link BI and the lever 94, urges the slide 52 to the left, as viewed in Fig. 2. Some what similarly, if there is no nickel in the slot 30 but there is a dime or a quarter in its respective slot in the slides, initial rotation of the lever moves the dime slide 56 to the left and through the bell crank lever III lowers the rod I01 and removes the roller IOI from engagement with hooked portion I00 freeing the shaft for a complete vending or change making cycle. Moving the operating slide 52 to the left also moves the slide rod I45 to the left, moving the cam portion I48 of the slide I45, camming the arm I30 of the coin detector finger upwardly and pivoting the coin detector plate to fully withdrawn position from the lower end of the coin tube 35. Movement of the dime slide 56 to the left, through the action of the pin H5 and the rod II3, pivots the bell crank lever III, lowers the rod I01, and pivots the lever I06 urging the lever I02 clockwise to a position retracting the roller IOI from hook engagement. The interconnection of the lever 85 and the link 9I by means of reception of the pin 88 in the slot 90 permits the emptying of the coin tube by manual reciprocation of the slide by the knob II'I without interference to movement by hook 500 and roller IOI engagement. On further rotation of the operating lever 29, the periphery of the disc 99 engages under the roller IOI holding the arm I02 to its clockwise pivoted position while the nickel gravitates from the slot 30 downwardly into the coin tube. As the nickel gravitates downwardly into the coin tube the triangular plate portion I40 of the coin detector finger I35 is in withdrawn position so that it will not interfere with the natural fall of the coin into the tube and permits the coin to fall to a horizontal position on the uppermost ooinof the stack of coins in the coin tube. On full operative rotation of the operating lever 29 and the operating shaft 26, the vending machine operatively connected thereto vends a fivecent article of merchandise, such as bottled beverages.

The vending machine may be also operated with coins of denominations larger than five cents, such as with a dime or quarter, in which instance the five-cent article is vended from the machine and change of the proper amount, in nickels, is delivered to the customer. Whenever it is necessary or desirable to operate the vending machine with a dime, the coin is inserted in the upper portion of the slug rejector I9 and gravitates downwardly along the dot-dash line, indicated at 22, in Fig. 1 of the drawing, and is normally delivered out of the lower right hand corner of the slug rejector. Whenever the dime rejecting finger I25 of the coin rejecting lever I20 is inserted into the path of the dime gravitating through the slug rejector I9, the dime is diverted and re- Jected out of the lower left hand corner of the slug rejector and is returned to the operator of the machine. If the dime is accepted by the slug rejector, it gravitates downwardly through one of the slots 30 in the disc 3| into the upper end of the dime chute 39 falling downwardly therethrough and is guided by the dime chute 39 into the vertically aligned dime slots 53 and 5'5 formed respectively in the operating slide 52 and the dime slide 56. With the dime thus located in the dime slots 53 and 57, movement of the operating slide 52 also causes movement of the dime slide 56 having driven connection therewith by means of the dime extending therebetween. On downward or clockwise rotation of the vending machine operating lever 29 and operating shaft 26, the initial rotation thereof moves the roller IIlI radially outwardly. from the operating shaft 26 to a position out of the rotative path of the notch I in the disc 99 through the movement of the operating slide moving the dime slide 56 by means of the rods lIlI through the pivoted bell crank lever I II operatively connected to the lever I92. With the roller I! thus moved out of the path of the hooked portion 55!] of the disc 99, the operating lever 29 may be rotated as for a vending cycle. During such operation the operating slide 52 and the dime slide 55 are moved longitudinally to coin releasing position through the rotative operation of the disc i5, cam slot I6, cam follower 8T, lever 85, link 9i, and lever 94 operatively associated with the operating slide 52. On sliding motion of the dime slide 56 to the left, the pocket 59 thereof, adapted to contain only one nickel, moves from a position under the coin tube to a position over the change receptacle 68 so that the nickel in the pocket 59 gravitates from the pocket downwardly into the change receptacle 68, which nickel is available to the operator of the vending machine as change for the dime deposited into the machine for the five-cent article of merchandise vended from the machine.

When the vending machine operating lever 28 has been rotated downwardly or clockwise to its fullest extent, the dime slots 53 and 5! are located over the dime depositing slot I9 in the bottom plate but with the dime still pinched in driving association between the dime slots 93 and 51. On the initial return upward motion, or counterclockwise rotation of the operating lever 29, the operating slide 52 is initially moved slightly inwardly, releasing the pinching action on the dime and permitting the dime to fall downwardly 10 through the dime depositing slot Ill into the coin depositing box I3.

The machine is somewhat similarly operated by the use of a quarter, with the vending machine vending a five-cent article of merchandise and returning four nickles in change therefor. The quarter is inserted into the upper portion of the slug rejector I9 and normally follows the dot-dotdash line 24 as shown in Fig. 1 of the drawing.

Whenever the quarter rejecting finger I24 is located in a position projecting into the slug rejector IS in the path of the quarter, the quarter is diverted from its normal path and rejected to the lower left hand corner of the slug rejector and returned to the operator of the vending machine. When accepted by the slug rejector I9, the quarter precipitates downwardly from the lower right hand corner of the slug rejector into one of the slots 39 forward in the disc EM and precipitates downwardly into the quarter chute 40 and is guided downwardly into the quarter slots 58, 54, and 63 formed respectively in the dime slide 56, operating slide 52, and quarter slide 62. With the quarter located in the quarter slots 56, 54, and 63, on initial operative rotation of the operating lever 29, the shaft 26, through levers and 94 with the link 9I connected therebetween, and the operating slide 52 drivingly connected to the dime slide 55 by means of the quarter in the quarter slots thereof, the dime slide 56 is moved longitudinally and horizontally to the left, as viewed in Fig. 2 of the drawings. Initial horizontal motion of the dime slide 56 actuates the lever I62 by means of the rods I91 and H3 moving the roller IIlI out of the rotative path of the notch I00 formed in the disc 99 so that the vending machine operating lever 29 may be rotated downwardly or clockwise to vending position. On movement of the operating slide 52 to change making position, both the dime slide 56 and the quarter slide 62 move horizontally therewith by means of the quarter located in the vertically aligned quarter slots of the slides. As the slides move horizontally the pocket 64 of the quarter slide and the pocket 59 of the dime slide, together containing four nickels for making change, are moved over the change receptacle 68 and the appropriate change deposited. The quarter is released and deposited through the slot "I2 into the coin depositing box 13 located therebelow upon initial counterrotation of the shaft 26 as described for the dime release.

It will be noted that when either a dime or a quarter is located respectively in the vertically aligned dime slots 53 and 5'! or the vertically aligned quarter slots 58, 54, and 63, that on initial movement of the operating slide 52, by rotation of the vending machine operating lever 29, that the roller Iill is rotated out of the path of the notch H10 in the disc 99 permitting the vending machine to be operated to vend articles from the vending machine. It will further be noted that the vending machine operating lever 29 may be rotated initially through a small arc until the notch I engages the roller IGI and during this rotative motion the operating slide 52 is moved horizontally sufiiciently to cause the cam portion I53 of the slide rod I45 to raise the arm I38 of the coin detecting finger I35 so that the triangular plate portion I49 of the coin detector finger is moved to fully withdrawn position and the collar I33 on the rod i3I moved upwardly rotating the coinrejecting lever I20 to withdrawn position with the quarter rejecting finger I24 and the dime rejecting finger I25 removed from the slug rejector I9. This rotation of the coin detector finger I35 moving the triangular plate portion I40 thereof to withdrawn position permits nickels deposited into the coin tube to gravitate therein unhampered by the presence of the coin detector finger therein so that each coin may lie fiatly against the stack of coins in the coin tube.

If there is an insufiicient number of coins in the coin tube, that is, when the uppermost coin in the coin tube is below the level of the lower end of the triangular plate portion I 40 of the coin detector finger, on return of the operating lever 29 and operating slide 52 to normal rest position, the triangular plate portion I40 moves interiorly of the coin tube causing the rod I30 to move downwardly and permitting the coin rejecting lever I20, through the urgency of the spring I28 to rotate to effective position with the fingers I24 and I25 projecting into the slug rejector I9. Thus when the quantity of change-making nickels within the coin tube is insufiicient for making change, the fingers I24 and I25, located in the slug rejector, cause all dimes and quarters inserted into the rejector to be rejected to the left of the slug rejector nd returned to the operator of the machine.

Whenever the lever 29 is moved sufficiently for the lock IIIII to pass the roller I I, the coin detector finger I35 is Withdrawn from the coin tube 35 until the lever is returned toward normal rest position. As previously described, this permits the unimpeded fall of nickels into the coin tube. When the lever is returned to rest position, the coin detector finger I35 is released for pivotal movement into the coin tube under the urging of the weight of the rod I3I imposed thereon, as shown in Fig. 7. If there is a sufiicient number of nickels in the tube 35 to make the appropriate change, the finger rests against the edges of such coins and is blocked from the coin tube. In this position, the coin rejecting fingers I24 and I25 are retracted and the mechanism is preconditioned for the acceptance of dimes and quarters as well as nickles. As shown in Fig. 9, when there is less than the predetermined number of nickels in the coin tube 35, the coin detector finger pivots into the coin tube, releasing the coin rejecting fingers I24 and I25 by the lowering of the collar I33, for movement into the dime and quarter paths, 22 and 24 respectively, under the urging of the spring I28.

From the foregoing description it will be seen that the present invention provides means in a coin responsive mechanism for rejecting coins when there is less than a predetermined number of coins in the mechanism, as in rejecting coins in a change making device when there is an insuflicient number of coins to make appropriate change. The coin detector of the present invention also provides means for accepting a dime or a quarter in the mechanism whenever there is a sufficient quantity of coins within the mechanism for making appropriate change. The coin detector also provides means for preventing interference with the natural fall of coins or nickels into the coin tube so that they will lie flatly and horizontally against coins already in the coin tube. It is emphasized that the nickels in the coin tube 35 do not operate the detector finger I35 but that the detector finger is positively withdrawn from the coin tube by movement of the slide rod I45 and permitted to return to the coin tube upon return of the slide rod to at-rest position only in the event less than the predetermined number of nickels are in the coin tube. The nickels have the effect of blocking return of the finger rather than operating said finger.
